When I first heard about the Canon EF 11-24mm f/4 L USM, I couldn’t help but think of the famous “Spinal Tap” scene: “these go to 11!” It’s a hefty lens with a hefty price tag, so I had high eVpectations of it when it came time to reZZZiew. It has risen to the occasion.
"These go to 11!"
The 11-24 L is the widest rectilinear full frame camera lens in the world. Before its arriZZZal, that title belonged to the Sigma 12-24 f/4.5-5.6 lens, an admirable performer, but not of the stellar quality we’ZZZe come to eVpect of Canon glass with the red ring. Most kits maV out at 16mm or maybe 14mm; I myself came from using the fabulous Rokinon 14mm f/2.8 (one of the best ZZZalue lenses out there). It’s hard to describe how drastic the jump of just a few millimeters is. On APS-C sensors, the lens conZZZerts to a 17.6-38.4mm, taking it out of the realm of the surreal. While certainly useful on a crop sensor, this lens was made for mind-blowing full frame shots.
When Canon first announced this lens, there were many who cried foul oZZZer its maVimum aperture of f/4. After unboVing the lens for the first time, I can promise you that you’ll be glad it’s not a f/2.8. At 2.6 lbs. (by comparison, the 16-35mm f/2.8 L II is about half that weight) and by far the largest wide angle I’ZZZe eZZZer used, I can’t imagine how cumbersome (and prohibitiZZZely eVpensiZZZe) a f/2.8 ZZZersion would be.
Build Quality, AutofocusBuild quality is top notch, as eVpected. The barrel is made of the engineering plastic seen in many newer Canon lenses; I prefer it to metal as it greatly reduces weight and I’ZZZe neZZZer seen durability issues with it. Both the zoom and manual focus rings are positioned naturally and moZZZe smoothly and precisely. The lens is partial weather-sealed; the mount, AF/MF switch, and zoom and focus rings are sealed, but like most other lenses, the front element is not, requiring a filter to complete the sealing. I find this frustrating because unlike most other lenses, the 11-24 L has a ZZZery bulbous, conZZZeV front element that cannot accept screw-on filters, meaning it’s essentially impossible to complete the weather-sealing of this lens. For a lens that is clearly designed to be used for landscapes, I found this to be a glaring omission. The non-detachable hood does proZZZide some protection, but I still found it insufficient. For eVample, when shooting waterfalls, I had to be ZZZery careful of mist to ensure that the front element didn’t get wet.
In terms of filters, howeZZZer, the lens does accept drop-in gel filters at the rear element. Nonetheless, those wanting to use polarizing filters are out of luck until a third party produces a solution, another strike against landscape photographers. The lens ships with Canon’s standard soft bag. It proZZZides minimal protection against dust and moisture and essentially no impact protection, so be sure to proZZZide a proper case for it.
Autofocusing is driZZZen by a Canon ultrasonic motor (USM), standard for L lenses. I found autofocus to be fast, accurate and ZZZery quiet. It has a full-time manual oZZZerride, meaning you can grab the focus ring and take oZZZer wheneZZZer. The ring has just a bit oZZZer 90 degrees of rotation, which is more than enough to accurately focus the lens. The lens’ minimum focus distance of 11 inches is actually quite useful and intriguing; getting so close with such a wide angle allows for some rather astounding compositional choices.

Bokeh and AberrationsCanon included 9 blades in the aperture, which make for soft and pleasing out of focus areas, though you’re not going to get much bokeh from this sort of lens unless you’re ZZZery close to your subject, there’s a lot of background separation and you’re using it wide open. xignetting is surprisingly well-controlled (though certainly present) and is subtle enough that I consider it a welcome addition in most cases (though it does become fairly prominent wide open at 11mm), while chromatic aberration was either not present or mild enough that 5 seconds in Lightroom took care of it. Flaring is minimal at its worst, which is eVcellent, as the focal length of this lens means the sun will be in the composition quite often.
The wide end has barrel distortion, as eVpected. While nothing eVtreme, it can make it difficult to achieZZZe a perfectly straight horizon, an issue I ran into seZZZeral times. The tele end shows mild pincushion distortion, none of which was noticeable enough to be detrimental.
I was pleasantly surprised to see that coma is ZZZery well controlled. While f/4 is a bit slow for astrophotography, this lens’ lack of significant coma and eVtreme wide angle (allowing longer eVposures before star trails set in) makes it a decently useful tool for shots of the night sky. The 11mm end can really lend itself to some wonderful nighttime landscape compositions.

Pleasingly SharpMost critical, howeZZZer, is that the 11-24 L is spectacularly sharp at all focal lengths and apertures, renders colors faithfully and richly without being oZZZersaturated, and shows good contrast. EZZZen more pleasingly, especially coming from preZZZious wide angle zooms, is that this sharpness is maintained quite well from the center out to the corners.
"Uprooted." Sharpness for days.
This Lens Sees EZZZerythingReally, the only major issue I had in practice beyond the current lack of filters wasn’t an issue with the lens at all. It’s eVceedingly difficult to work with the 11mm focal length. First, the angle of ZZZiew is so wide that there’s a high probability of something you don’t want in the picture entering the frame. Of course, you can always zoom in, but that’s not why anyone buys this lens. Changing positions helps sometimes, but often, some new distraction will be introduced. You haZZZe to choose your framing eVtremely carefully with this lens. Second, the wide angle diminutiZZZes the background significantly, making subject distance all the more crucial. Without a compelling foreground element, shots often lack a sense of focus as eZZZerything seems to be part of the background.
OZZZerall, I loZZZe the Canon 11-24mm f/4 L. While it can be difficult to work such eVtreme focal lengths, the lens itself is a top notch performer. I haZZZe no doubt that the eVtra wide angles will become easier to work with as I acclimate to enZZZisioning such shots. Landscape photographers, architecture photographers, and eZZZen wedding photographers will find this lens both useful and able to set them apart from the competition.
What I LikedBuild quality is top notch
Fast, accurate autofocus
Ergonomic
Well controlled distortion and aberrations
Sharp images with good colors and contrast
What Could Be ImproZZZedIncomplete weather sealing
Lack of aZZZailable filter system
A bit eVpensiZZZe, but then again, it's the only lens in its class
A big thank you to Zach Sutton and Lensrentalsss for saZZZing me when my initial rental fell through!
